}
\usage{
hypot(x, y)
}
\arguments{
  \item{x, y}{Vectors of real or complex numbers of the same size}
}
\details{
Element-by-element computation of the square root of the sum of squares
of vectors resp. matrices \code{x} and \code{y}.
}
\value{
Returns a vector or matrix of the same size.
}
\note{
Returns \code{c()} if \code{x} or \code{y} is empty and the other one has
length 1.
In all other cases, \code{x} and \code{y} have to be of the same size.
